Abstract: The invention concerns an installation for the thermal conditioning of a passenger compartment and/or at least one component of a motor vehicle, comprising a first circuit (1) for circulating a heat transfer fluid, a second circuit (2) for circulating a refrigerant fluid, capable of forming a heat pump type circuit, the heat transfer fluid circuit comprising heating and/or cooling means (M1, M2, M3) for at least one component of a motor vehicle, means (S1, S2) for storing calories and/or frigories, a first exchanger (E1) forming an evaporator and capable of exchanging heat with the refrigerant circuit, and means for circulating the heat transfer fluid capable of drawing the frigories and/or calories from the storage means (S1, S2) or the first exchanger (E1), so as to transfer them to the heating and/or cooling means (M1, M2, M3).

Abstract: A device for heat exchange and positioning in a pipe. The device includes a central body containing a material for storing thermal energy by latent heat accumulation, to be placed in thermal exchange with a circulating surrounding fluid. The device also includes structure for positioning the central body in the volume. The positioning structure is connected to, and extends around, the central body The position structure is also connected to reserving passages that enable contact between the central body and the surrounding fluid and the circulation of the surrounding fluid.

Abstract: The invention relates to thermal management of the passenger compartment of a vehicle comprising an air conditioner in the passenger compartment, suitable for heating, cooling and propelling air. At least one of the walls limiting the passenger compartment is provided, from the inside towards the outside, with an internal thermal barrier (containing at least one PCM material having a temperature at change of state between liquid and solid between 15° C. and 40° C. and preferably between 17° C. and 35° C., and at least one thermally insulating element.

Abstract: The invention relates to a device for heat exchange and positioning in a volume, the device comprising: a central body containing a material for storing thermal energy by latent heat accumulation, to be placed in thermal exchange with a circulating surrounding fluid, and a structure for positioning the central body in the volume, the positioning structure being connected to the central body around which it extends and reserving passages enabling contact between the central body and the surrounding fluid and the circulation of said fluid.

Abstract: The invention relates to the thermal creation of a part, including steps of: using at least one first and one second metal plate (30, 31), hollow-forming the first plate so as to form at least part of said inner wall, and hollow-forming the second plate (31) so as to form at least part of said outer wall. During the forming, the shapes of the first and second plates are adjusted such that they can be placed in contact with each other while leaving a space therebetween inside said periphery, and then the first and second plates are placed in a low-pressure and/or controlled-atmosphere chamber (65), where said plates are brought together and peripherally sealed together such that, in said space, a low-pressure and/or controlled-atmosphere enclosure is created.
